Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning system.
When the air conditioning system is turned on, cool dehu -
midified air will flow through the outlets into the cabin. For
improved fuel economy, press the A/C button to turn off the
air conditioning and manually adjust the blower and airflow
mode settings. Also, make sure to select only Panel, Bi-Level,
or Floor modes.
NOTE:
• For Manual Climate Controls, if the system is in Mix, Floor
or Defrost Mode, the A/C can be turned off, but the A/C
system shall remain active to prevent fogging of the
windows.
• If fog or mist appears on the windshield or side glass,
select Defrost mode, and increase blower speed if needed.
• If your air conditioning performance seems lower than
expected, check the front of the A/C condenser (located in
front of the radiator), for an accumulation of dirt or insects.
Clean with a gentle water spray from the front of the radi -
ator and through the condenser. MAX A/C
MAX A/C sets the control for maximum cooling perfor -
mance.
Press and release to toggle between MAX A/C and the prior
settings. The button illuminates when MAX A/C is on.
In MAX A/C, the blower level and mode position can be
adjusted to desired user settings. Pressing other settings will
cause the MAX A/C operation to switch to the selected
setting and MAX A/C to exit.
Recirculation
In cold weather, use of Recirculation mode may lead to
excessive window fogging. The Recirculation feature may be
unavailable (button on the touchscreen greyed out) if condi -
tions exist that could create fogging on the inside of the
windshield.
On systems with Manual Climate Controls, if equipped, the
Recirculation mode is not allowed in Defrost mode to
improve window clearing operation. Recirculation is
disabled automatically if this mode is selected. Attempting
to use Recirculation while in this mode causes the LED in the
control button to blink and then turns off.

Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor -
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration of
coolant is used. Use of the Air Recirculation mode during
Winter months is not recommended, because it may cause
window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again. Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select Defrost
or Mix mode and increase the front blower speed. Do not use
the Recirculation mode without A/C for long periods, as
fogging may occur.
CAUTION!
Failure to follow these cautions can cause damage to the
heating elements:
• Use care when washing the inside of the rear window.
Do not use abrasive window cleaners on the interior
surface of the window. Use a soft cloth and a mild
washing solution, wiping parallel to the heating
elements. Labels can be peeled off after soaking with
warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the window.
• Keep all objects a safe distance from the window.

Power Windows
Power Window Controls
Power Window Switches
The power window controls located on the driver's door trim
panel have up-down switches that give you fingertip control of
all power windows. There is a single opening and closing
switch on the front passenger door for passenger window
control and on the rear doors for rear window control. The
windows will operate when the ignition switch is turned to the ON/RUN or ACC position, and for up to 10 minutes after the
ignition is turned OFF or until a front door is opened.
NOTE:
The Key Off Power Delay feature will allow the power
windows to operate for up to 10 minutes after the ignition is
turned OFF. This feature is cancelled when either front door
is opened.
Auto-Down
Both the driver and front passenger window switch have an
Auto-Down feature. Push the window switch past the first
detent, release, and the window will go down automatically. WARNING!
Never leave children unattended in a vehicle. Do not
leave the key fob in or near the vehicle or in a location
accessible to children, and do not leave the ignition of a
vehicle equipped with Keyless Enter-N-Go in the ACC
or ON/RUN mode. Occupants, particularly unattended
children, can become entrapped by the windows while
operating the power window switches. Such entrapment
may result in serious injury or death.

GETTING TO KNOW YOUR VEHICLE 93
To cancel the Auto-Down movement, operate the switch in
either the up or down direction and release the switch.
To stop the window from going all the way down during the
Auto-Down operation, pull up on the switch briefly.
To open the window part way, push to the switch to the first
detent and release it when you want the window to stop.
